The IKS SuvwI' was a warship in service to the Klingon Empire's Defense Force in the 23rd century.

By 2267 the Suvwi' was under the command of Captain Kang. In that year, the SuvwI' protected the IKS Gr'oth during its final battle against Tholian forces. Before the Gr'oth was destroyed, Koloth and his crew were beamed aboard the SuvwI'. (TOS - Strange New Worlds 9 short story: "A Bad Day for Koloth")
